According to the packaging technology of double-sided cells, it can be divided into double-sided double-glass components and double-sided (with frame) components. The structure of double-sided double-glass components includes: double-layer glass + frameless structure; double-sided (with frame) components adopt Transparent back panel + frame form, etc. The double-glass bifacial module with mainstream structure has the advantages of long life cycle, low attenuation rate, weather resistance, high fire rating, good heat dissipation, good insulation, easy cleaning, and higher power generation efficiency.
As the name implies, bifacial modules are modules that can generate electricity on both sides. When the sun shines on the bifacial module, part of the light will be reflected by the surrounding environment to the back of the bifacial module, and this part of the light can be absorbed by the cell, thus making a certain contribution to the photocurrent and efficiency of the cell.
What is the maximum wattage of 210 components
The maximum achieved is 600 watts.
Based on 210mm large-size silicon wafers, innovative non-destructive cutting technology and high-density packaging technology are applied, low voltage, high string power, single-string module power increased by 34%, the maximum power can reach 670W, and the efficiency is as high as 21.6%. Leading the industry into a new era of photovoltaic 600W+.
Half-chip modules using G12 silicon wafers (side distance 210mm) can achieve a module power of nearly 600W. The disadvantages of this product are high internal losses caused by high current, and the risk of hot spots and junction box reliability is significantly increased. It is considered that the rough curve has significantly improved the rock density.
